PIC32MX564F128LT-V/BG Overview
A 32-bit microcontroller (MCU) is a single-chip computer built around a 32-bit data path and registers, allowing larger address spaces (>4 GB), richer instruction sets, and higher throughput than 8-bit or 16-bit MCUs. The PIC32MX family specifically uses the MIPS32 M4K core licensed from MIPS Technologies, combining Harvard-architecture performance with deterministic interrupt response. Within the broader taxonomy, the PIC32MX5xx belongs to: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS MCU -> PIC32 -> PIC32MX5xx. It is suitable as a general-purpose embedded controller that bridges 16-bit PIC24/dsPIC performance with ARM Cortex-M3 alternatives.
Key features include 128 KB Flash program memory, 32 KB SRAM, full-speed USB-OTG on-chip transceiver, CAN 2.0B module, 16-channel 10-bit 1 MSPS ADC, four DMA channels for CPU-offload data movement, two UART, two SPI, two I2C, five 16-bit timers/captures, and parallel master port. The device includes fail-safe clock monitoring, two internal oscillators (8 MHz and 31 kHz), a hardware real-time clock/calendar with alarms, and a watchdog timer with a dedicated RC oscillator. Pin compatibility with 16-bit PIC MCUs simplifies migration from dsPIC/PIC24 designs.
The architecture pairs a 5-stage MIPS32 M4K pipeline with single-cycle hardware multiply/divide and a tightly-coupled prefetch cache, giving Dhrystone 2.1 performance of approximately 1.5 DMIPS/MHz. The 10-bit successive-approximation ADC plus four-channel DMA enables continuous analog sampling without CPU intervention, while USB-OTG and CAN together make the part a strong fit for industrial bridging nodes.
Typical applications include USB peripherals (HID, CDC, MSD, audio), CAN-based automotive body controllers, industrial PLCs and sensor hubs, and medical instrumentation requiring deterministic USB connectivity. The wide peripheral set also fits smart-grid metering and HMI panels.
Design tip: BGA packages require via-in-pad or microvia PCB processes; ensure the design rules for the TFBGA-121 footprint match Microchip's recommended land pattern and that the inner balls are inspected post-reflow using X-ray.

USB HID Peripheral Devices
The PIC32MX564F128LT-V/BG's integrated USB 2.0 Full-Speed OTG transceiver eliminates the need for an external PHY, reducing BOM cost by approximately $0.50-$1.00 versus discrete-USB designs. Its 80 MHz MIPS32 M4K core at 1.5 DMIPS/MHz delivers sufficient throughput for HID class descriptors, HID reports at 1 kHz polling, and CDC virtual COM port bridges simultaneously. The 4-channel DMA offloads USB endpoint buffer transfers from the CPU, freeing cycles for application logic such as keypad scanning or LED matrix driving. Compared to STM32F0 alternatives, the PIC32MX564F128LT-V/BG offers Microchip's mature USB stack with proven HID, CDC, MSD, and audio class drivers, making it ideal for industrial keypads, barcode scanners, and human-interface peripherals.

CAN-based Automotive Body Controllers
The PIC32MX564F128LT-V/BG integrates both CAN 2.0B and USB-OTG on-chip, making it a single-chip bridge for automotive body control modules that need to communicate over CAN while exposing diagnostics over USB. Its -40C to +105C V-grade operating temperature suits under-hood and cabin environments, and 32 KB SRAM supports CAN message buffering plus USB-CDC command parsing concurrently. The 16-channel 10-bit ADC handles multiple sensor inputs (temperature, position, current) without external multiplexer ICs. Compared to PIC18F alternatives with CAN, the PIC32MX564F128LT-V/BG delivers higher DMIPS/MHz and supports OBD-II stacks plus UDS firmware updates via USB more comfortably.
Recommended
Industrial PLC and Sensor Hub
In industrial PLC applications, the PIC32MX564F128LT-V/BG's 85 I/O pins and 16-channel 10-bit ADC at 1 MSPS enable direct connection to multiple analog sensors, digital inputs, and relay outputs without external I/O expanders. The 4-channel DMA continuously streams ADC conversions into RAM at full sample rate without CPU intervention, freeing the 80 MHz core for ladder-logic or IEC 61131-3 runtimes. Hardware RTCC with alarms and the fail-safe clock monitor provide industrial-grade reliability for unattended installations. Compared to PIC24FJ alternatives, the PIC32MX564F128LT-V/BG delivers higher throughput for Modbus TCP gateway firmware and supports Microchip's Harmony TCP/IP stack for networked PLCs.
Recommended
Medical Instrumentation with USB Data Logging
The PIC32MX564F128LT-V/BG's USB-OTG Full-Speed interface and 10-bit ADC at 1 MSPS make it well-suited to medical instruments that stream waveforms to a host PC for analysis, such as pulse oximeters, spirometers, or low-cost ECG front-ends. Its 32 KB SRAM buffers multiple seconds of sampled data at typical 100 Hz to 1 kHz medical rates, while 128 KB Flash holds USB stack plus device firmware. The deterministic interrupt response of the MIPS32 M4K core ensures accurate timing of ADC sample triggers. Compared to 8-bit PIC16 alternatives, the PIC32MX564F128LT-V/BG runs USB CDC stacks at higher sustained throughput and supports firmware updates over USB without external bootloader ICs.

Smart Grid Energy Metering
The PIC32MX564F128LT-V/BG combines a 10-bit ADC with USB-OTG and CAN in one package, which is ideal for single-phase or polyphase smart meters that need to log energy data locally and report it over powerline communication or wireless bridges. Its hardware RTCC supports time-of-use billing schedules without external RTC ICs, and the fail-safe clock monitor provides automatic switchover to the internal 8 MHz oscillator if the crystal fails. The 80 MHz core delivers enough throughput for FFT-based harmonic analysis at sampling rates up to 1 MSPS. Compared to MSP430 energy-meter alternatives, the PIC32MX564F128LT-V/BG offers more GPIO, on-chip USB, and CAN for a comparable unit price.
Recommended
HMI Touch Panel Controller
The PIC32MX564F128LT-V/BG's 85 I/O pins and 80 MHz MIPS core enable cost-effective HMI panels that drive character LCDs, segmented displays, or small TFTs while scanning keypads and rotary encoders. Its DMA channels move display data to SPI-driven displays without CPU overhead, and the 32 KB SRAM holds double-buffered frame data for animated menus. Compared to Cortex-M0 HMI controllers, the PIC32MX564F128LT-V/BG offers more SRAM, more DMA channels, and proven USB-CDC for HMI configuration tools. The V-grade temperature range supports industrial control cabinet environments from -40C to +105C.

Design Notes
The 121-ball TFBGA package requires microvia or via-in-pad PCB technology. Per Microchip's PIC32MX5xx hardware design guide, the recommended land pattern uses 0.4 mm solder mask-defined pads with 0.5 mm non-solder mask-defined (NSMD) pads to ensure reliable BGA reflow. Below the package, route signal traces on inner layers; keep the inner balls' thermal pads connected to a continuous ground pour for thermal dissipation. X-ray inspection after reflow is strongly recommended because BGA defects cannot be visually inspected.
The PIC32MX564F128LT-V/BG requires a 2.3 V to 3.6 V supply on VDD, with a separate AVDD pin for the ADC that benefits from an LC filter (10 uH + 10 uF) to reduce switching noise from digital logic. Place a 0.1 uF ceramic decoupling capacitor within 5 mm of each VDD pin and a bulk 10 uF tantalum or ceramic capacitor near the regulator output. The USB transceiver requires VBUS detection (5 V tolerant); add a 10 kohm pull-down on VBUS to ensure correct disconnect detection per USB 2.0 spec.
Route the 80 MHz crystal traces (OSC1/OSC2) as short, symmetric pairs with a grounded guard ring on both sides; keep them away from switching I/O lines to minimize EMI. The USB DP/DM traces should be 90 ohm differential with continuous reference plane on the layer below. According to Microchip's PIC32MX5xx layout checklist, keep ADC analog inputs separated from digital signals and surrounded by a ground pour that connects only at the MCU's AGND pin (star-ground topology).
Do not enable the USB module without first configuring the PLL and I/O mapping correctly; failure to wait for PLL lock causes USB enumeration failures. Avoid using the internal 8 MHz oscillator for USB operation - it does not meet the USB Full-Speed accuracy requirement; use the 48 MHz PLL driven from an 8 MHz crystal instead. According to the Microchip PIC32MX5xx errata, early silicon revisions had ADC DMA conflicts at sample rates above 500 kSPS; ensure the device revision is A3 or later for full 1 MSPS DMA operation.
Compliance Information
RoHS compliant per Microchip product page. V-grade operating temperature (-40C to +105C) supports industrial use; for AEC-Q100 automotive qualification, dedicated PIC32MX5xx -VAO variants are required instead.
